Review on Astro 9445 Titanium Step Drill by Cody Duncan

Industrial and scientific? More like industrial and defective! After I put it to the test, I realized these so-called "titanium" drill bits were no match for the job .The only pro is that they were cheap but you get what you pay for. The cons? The bits snapped off and dulled quickly, leaving me with a useless product and a frustrating job to finish. Save your money and invest in a better quality product from a reputable brand. These drill bits are a waste OF time and money..
